Review on 🔒 Zyxel USG Flex 100 (USG40 v2): Top-rated UTM Firewall Hardware Ideal for 25 Users [USGFLEX100] by Brandon Addison

I love ZyXEL firewalls, I've installed literally hundreds of them at different companies over the years, all different models and they are very stable and reliable. I even had a few lightning strikes and kept running. They'll last forever or until you decide to upgrade to a faster newer model. Keep in mind that these are very powerful professional grade firewalls that can frustrate the average consumer with minimal computer networking knowledge/training. If you know how to program business-class firewalls from SonicWall, Cisco ASA, Fortigate, etc., you won't have a problem.
